I created OLS multivariable regression model and almost all looks pretty good. All variables are significant, R-squared - also good, near to 0.8. It was a little problem with heteroskedaticity, but with logarithms i fixed it. But another problem still exists. Residuals of my model are still non normal and I dont know what i need to do. I checked correlation of residuals and other variables and there are no correlation.

Is it a very big problem or I can ignore it? Maybe somebody of you could help me to fixed it.

Thanks for advice and help!

Right here is the graph of my residuals
